Actually it is using globbing to do what you would normaly do with
split().
$ perl -MO=Deparse -e'while ( < i am fred flintstone >) { print
">$_<\n" }'
while (defined($_ = CORE::GLOBAL::glob(' i am fred flintstone ',
0))) {
print ">$_<\n";
}
-e syntax OK

Which is why the second regex is failing because it is trying to match
two words.
